• ¼ cup neutral oil, such as canola or avocado

How to Make Crackle-Topped Rhubarb Coffee Cake – Step by Step

Preparation

Step 1: Preheat your oven to 350°F (175°C). Lightly grease a 9-inch round cake pan or springform pan and line the bottom with parchment paper for easy removal.

Step 2: Prepare your rhubarb by washing thoroughly and trimming away any leaves (which are toxic) and tough ends. Cut into ½-inch pieces to ensure even distribution throughout the cake.

Making the Cake Batter

Step 3: In a large mixing bowl, whisk together the dry ingredients: flour, sugar, baking powder, cinnamon, and salt until well combined.

Step 4: In a separate medium bowl, beat the egg lightly, then add buttermilk, oil, and vanilla extract. Whisk until smooth and well blended.

Step 5: Pour the wet ingredients into the dry ingredients and stir gently with a rubber spatula just until combined. The batter will be thick. Be careful not to overmix, as this can make your Crackle-Topped Rhubarb Coffee Cake tough.

Step 6: Fold in the chopped rhubarb pieces until evenly distributed throughout the batter.

Creating the Crackle Topping

Step 7: In a small bowl, mix together the ¼ cup sugar and ½ teaspoon cinnamon for the topping.

Assembling and Baking

Step 8: Pour the batter into the prepared pan, spreading it evenly with a spatula. The batter will be thick, so take your time to create an even layer.

Step 9: Sprinkle the cinnamon-sugar mixture evenly over the top of the batter. This creates the signature crackling effect that makes this Crackle-Topped Rhubarb Coffee Cake so special.

Step 10: Bake for 35-40 minutes, or until a toothpick inserted in the center comes out clean and the top is golden brown with a beautiful crackled appearance.

Step 11: Allow the Crackle-Topped Rhubarb Coffee Cake to cool in the pan for 15 minutes before transferring to a wire rack to cool completely.

Pro Tips for Making the Best Crackle-Topped Rhubarb Coffee Cake

• For the most vibrant color in your Crackle-Topped Rhubarb Coffee Cake, look for the reddest stalks of rhubarb you can find at your market.
• The key to achieving the perfect crackle top is ensuring your oven is fully preheated before baking. This allows the sugar topping to begin caramelizing quickly.
• Don’t worry if your rhubarb releases moisture during baking – this actually contributes to the moist texture of the Crackle-Topped Rhubarb Coffee Cake.
• For an extra special Crackle-Topped Rhubarb Coffee Cake, add ¼ teaspoon of cardamom to the cake batter, which pairs beautifully with the rhubarb.
• To make this Crackle-Topped Rhubarb Coffee Cake ahead of time, prepare the batter up to Step 7, then refrigerate overnight. Allow it to come to room temperature for 30 minutes before adding the topping and baking.
